old said: (quoted from post at 12:34:42 11/24/14) I have to disagree with you since if you compare a 24HP lawn more to the 8N the lawn mower does not come close as for TRUE HP
You can disagree all you want but you will still be wrong. This is not a matter of opinion - it is physics.
In the 18th century an engineer named James Watt proposed a new unit of measurement for power (work x time) in order to compare the amount of work a new fangled invention called a steam engine couid produce to the amount of work produced by the commonly used draft horse. His definition for this unit of power measurement was EXACTLY the one I gave you earlier:
1 horse power = 33,000 lb/ft per minute.
That is torque x time = power and has been and still is the definition of mechanical hose power used by engineers since 1750.
If you do not understand why a modern lawn tractor engine running at 3600 RPM is producing the same TRUE engine horsepower as the L-head in an 8N tractor running at 2000 RPM you need to brush up on your physics.
